TopologieSonstige Topologie


The AEM10941 is an integrated energy management circuitthat extracts DC power from up to 7-cell solar panels to si-multaneously store energy in a rechargeable element and sup-ply the system with two independent regulated voltages. TheAEM10941 allows to extend battery lifetime and ultimatelyeliminates the primary energy storage element in a large rangeof wireless applications, such as industrial monitoring, geoloca-tion, home automation, e-health monitoring and wireless sen-sor nodes.
